LUDGER GENEST, OF HULL, CANADA.

HYDRANT AND STAND-PIPE.

SPECIFICATION forming part of Letters Patent No. 604,611, dated May 24, 1898. Application tiled April 14, 1897. Serial Ilo. 632,166. (No model.) Patented in Canada October 21, 1896, No. 53,845.

To all whom, it may concern:

Be it known that I, LUDGEE GENEsT, of the city of I-Iull, in the Province of Quebec, in the Dominion of Canada, have invented certain new and useful Improvements in IIydrants and Stand-Pipes, (for which I have obtained a patent in Canada, No. 53,845, bearing date of October 21, 1896;) and I do hereby declare that the following is a full, clear, and eXact description of the same, reference being had to the accompanying drawings, forming apart hereof.

My invention, which will be hereinafter fully set forth and claimed, relates to hydrants and stand-pipes for drawing water from water mains and pipes.

The object of my invention is to prevent the water in hydrants and stand-pipes from freezing when turned off.

Figure 1 is a vertical central section of a hydrant showing my improvement. Fig. 2 is a horizontal section of the same on line 2 2, Fig. 1; and Fig. 3 is a vertical central section of the lower part, as Fig. 1, but without the jacket.

A is the water-main, which is ordinarily connected with the base B of the hydrant by a service-pipe C. D is the main body of the hydrant, ordinarily secured into the base or valve-chamber B, as shown in Fig. 3; but I prefer when constructing new hydrants to provide its lower end with a jacket E, which I secure into and connect with the base B, said jacket providing a space 2 around the lower end of said main body, the base being made correspondingly larger. Said space 2 being filled with air, which cannot escape because closed at the top, forms an air-space at the upper portion, which the water cannot enter, and said air-space forms a non-conducting or insulating medium around the lower part of the main body of the hydrant. F is a casing fitting the head or upper bulge of the main body of the hydrant and below into the widened mouth of the base B and forming an air-space around said body. G is the valve-spindle with valve G fitted in the ordinary manner, and D is the drain-pipe. All this, with the exception of the jacket E, is of the ordinary construction.

In order to prevent the water in the base or valve-chamber B and service-pipe C being stagnant,I make a second connection between the main A and said base a little distance from the service-pipe C by a circulating-pipe II, entering the `base B below the valve G. This causes a circulation throughthe base B and prevents the water from freezing. This circulating-pipe H may be applied to existing Vhydrants without the jacket Eand is equally effective without the latter, but said jacket forms an additional safeguard. The jacket E is also particularly useful if the hydrant stands in a low place where subsoil-watcr is apt to drain into the lower part of the hydrant through the drain-pipe D'.

I claim as my invention- 1. In a hydrant, the combination with its main body, of a jacket at its lower end formingV a space around said lower end and adapted to be securedin the base, a base into which said jacket is secured, a service-pipe connecting said base with the main and a circulatingpipe connecting said base with the main a little distance from said service-pipe, independently of the latter, substantially as set forth.

2. In a hydrant, the combination with the main body and the base of a jacket at the lower end of said main body closed at the top and open below and adapted to form an airspace around said lower end and said jacket forming the connection with said base or valve-chamber, substantially as set forth.

In testimony whereof I have signed in the presence of the undersigned witnesses.

LUDGER GENEST.
